Definitions

• the invention relates to a wedge connector with insulation perforating device, for connecting electrical conductors provided with an insulating covering, comprising: [a] an external C-shaped member, determining two first curved wings, the respective bottoms of which define mutually inclined longitudinal lines; [b] a wedge member having two mutually inclined concave active edges; and [c] at least one intermediate member comprising electrically conducting material and which is adapted to be located between said external member and said wedge member.
• Document EP 0 810 688 describes a connector for obtaining an electrical bridge between two electrical conductors having an insulating covering.
• This bridge is based on an electrically conducting intermediate member provided externally with perforating means which may be applied to portions of two insulated conductors, located respectively in the wings of the external member. The insertion of a wedge in the intermediate member causes the engagement of these perforating means with the insulating covering and the consequent establishment of an electrical connection between both conductors.
• this connector has the drawback that it allows a large relative sliding between the conductor and the perforating means, whereby it frequently causes serious tears in the insulating covering, which is an unfavourable circumstance as far as obtaining a long-lasting connection is concerned.
• said intermediate member is C-shaped and forms two second curved wings between which there extends a generally flat portion.
• Each of said two second curved wings is adapted for surrounding in part a portion of one of said electrical conductors and each of them is provided with said perforating teeth projecting internally from the concave surface thereof.
• Said perforating teeth preferably form pairs of teeth, in such a way that both teeth of one same pair project from respective facing longitudinal portions of a wing, in which there is formed an opening.
• a stop member formed by a fold which by engagement with a transverse edge of said external member, is adapted to limit the sliding of said intermediate member relative to said external member.
• Figure 1 is an exploded perspective view of the constituent members of the connector of the invention.
• Figure 2 is a cross section view on the line ll-ll of Figure 3.
• Figure 3 is a front elevation view of the intermediate member. -3-
• the connector of the invention comprises an external member 2, an intermediate member 4 and a wedge member 6.
• the external member 2 is C-shaped. It is intended with this expression to signify that the cross sections of the external member would reproduce the shape of this letter.
• the external member is formed by a plate 8 from which there extend two first curved wings 10 and it is pointed out that the bottoms 12 of these wings 10 define longitudinal lines inclined towards each other. As a result of this, the two transverse edges of the plate 8 are unequal.
• the wedge member 6 is provided with two active edges 14 forming respective concavities and which are inclined towards each other, in an angular magnitude substantially equal to that defined by the bottoms 12 of the wings 10 of the external member 2.
• the intermediate member 4 comprises electrically conducting material. It is also C-shaped, i.e., it is also formed by a plate 16 from which there extend two second wings 18, each of which is adapted to surround in part a portion of a corresponding electrical conductor 20, covered by an insulating covering 21. As described hereinafter, when the connector is in use, the intermediate member 4 is located between the external member 2 and the wedge member 6, whereby there is an inclination between the wings 18 similar to those of the other two members. Because of this inclination, the plate 16 is provided with two transverse end edges 28, 30 ( Figure 2), of different length.
• Each of the wings 18 of the intermediate member 4 is provided with a plurality of perforating teeth 22 which are capable of perforating the insulating covering 21 and which project inwardly of a wing 18, from the concave internal surface thereof.
• These teeth 22 preferably form pairs, in such a way that two teeth 22 of one same pair project from facing longitudinal portions 24a, 24b, forming an opening 26.
